Stiles not sure if romance is still on

The Bourne Identity star Julia Stiles' movie success could force her to break up with her boyfriend, student John Mays.

The sexy actress, 23, has been away from her lover for four months while she stars in London play Oleanna, and fears she will have to end their relationship when she returns to him in New York, because Mays is insecure about her fame, constant travelling, sexy co-stars and staggering fortune.
